Bill Gates and Warren Buffett want to build a new kind of nuclear reactor to generate electricity. Why? Because the wind doesn’t always blow and the sun doesn’t always shine. They intend to plunk their new toy down in the state of Wyoming on the former site of a coal-fired generating plant.
“This is our fastest and clearest course to becoming carbon negative,” says Wyoming’s governor Mark Gordon. “Nuclear power is clearly a part of my all-of-the-above strategy for energy.” Wyoming is the top coal producing state in America.
According to The Guardian, the new facility will be a joint venture between TerraPower, founded by Gates 15 years ago, and PacifiCorp, a Berkshire Hathaway-owned utility that serves customers in Wyoming, Idaho, Utah, California, Oregon, and Washington.
Small advanced reactors, which run on different fuels than traditional reactors, are regarded by some as a critical carbon-free technology that can supplement intermittent power sources like wind and solar as states strive to cut emissions that cause climate change. “We think Natrium will be a game-changer for the energy industry,” Gates told a media conference in Cheyenne, Wyoming this week.
The Guardian says the new generating station will produce 345 megawatts of electricity, but the output can be boosted by a molten salt energy storage component to 500 megawatts. The primary feature of the so-called Natrium technology is that it uses sodium to cool the reactor instead of water. Natrium is the Latin word for sodium, which is why its symbol on the periodic table of elements is Na.
Chris Levesque, TerraPower CEO, told the press this week the demonstration plant will cost about $1 billion and will take about seven years to build. “We need this kind of clean energy on the grid in the 2030s,” he told reporters. Actually, Chris, we need clean energy on the grid now, not 7+ years from now. A billion dollars would buy more than 500 MW of power and have it online, together with grid storage batteries, in a lot less time. Why wait?
Natrium Technology
I am not a nuclear engineer nor am I a rocket scientist, so I have to rely on Wikipedia to inform me about some things (I contribute $5 a month to support Wikipedia and encourage you to do the same).
The primary advantage of liquid metal coolants, such as liquid sodium, is that metal atoms are weak neutron moderators. Water is a much stronger neutron moderator because the hydrogen atoms found in water are much lighter than metal atoms, and therefore neutrons lose more energy in collisions with hydrogen atoms.
This makes it difficult to use water as a coolant for a fast reactor because the water tends to slow (moderate) the fast neutrons into thermal neutrons (though concepts for reduced moderation water reactors exist).
Another advantage of liquid sodium coolant is that sodium melts at 371K and boils / vaporizes at 1156K, a total temperature range of 785K between solid / frozen and gas / vapor states. By comparison, the liquid temperature range of water (between ice and gas) is just 100K at normal, sea-level atmospheric pressure conditions. Despite sodium’s low specific heat (as compared to water), this enables the absorption of significant heat in the liquid phase, even allowing for safety margins. Moreover, the high thermal conductivity of sodium effectively creates a reservoir of heat capacity which provides thermal inertia against overheating.
Sodium also need not be pressurized since its boiling point is much higher than the reactor’s operating temperature, and sodium does not corrode steel reactor parts.[2] The high temperatures reached by the coolant (the Phénix reactor outlet temperature was 560° C) permit a higher thermodynamic efficiency than in water-cooled reactors. The molten sodium, being electrically conductive, can also be pumped by electromagnetic pumps.
Disadvantages
A disadvantage of sodium is its chemical reactivity, which requires special precautions to prevent and suppress fires. If sodium comes into contact with water it reacts to produce sodium hydroxide and hydrogen, and the hydrogen burns when in contact with air.
This was the case at the Monju Nuclear Power Plant in a 1995 accident. In addition, neutron capture causes it to become radioactive; however, activated sodium has a half-life of only 15 hours. Another problem is sodium leaks which are regarded by a critic of fast reactors, M.V. Ramana, as “pretty much impossible to prevent.”
Fuel Used
Wikipedia adds that a natrium facility that generates less than 500 MW of electricity uses “uranium-plutonium-minor-actinide-zirconium metal alloy fuel, which is supported by a fuel cycle based on pyrometallurgical reprocessing in facilities integrated with the reactor.” I don’t know about you, but the words “uranium” and “plutonium” don’t sound like “different fuels compared to traditional nuclear reactors.”
The Guardian points out that nuclear power experts have warned that advanced reactors could have higher risks than conventional ones. Fuel for many advanced reactors would have to be enriched at a much higher rate than conventional fuel, meaning the fuel supply chain could be an attractive target for militants looking to create a crude nuclear weapon. And don’t even be concerned about Russian hackers. We know those malefactors only like to interrupt gasoline pipelines and beef processing plants. Pooty Poot and his henchmen would never stoop so low as to hack a nuclear power plant…would they?
People always rush to criticize Tesla for selling emissions credits, but no one wants to talk about the $80 million the US Department of Energy has already invested in TerraPower with millions more coming in the future. No one would expect Bill Gates and Warren Buffett — two of the richest white men in history — to foot the bill for their boondoggles all by themselves, would they?
All Of The Above
The key to understanding this story is found in Governor Gordon’s use of the words “all of the above.” That’s free market speak for “We’re happy to have a piddly little 350 MW facility of over here, just so long as we can continue supporting coal- and gas-powered generating plants that churn out hundreds of gigawatts over there.” In other words, it’s a smokescreen designed to allow fossil fuel interests to kick the can down the road a little further and add some greenwashing to their corporate portfolios at the same time.
Being rich does not necessarily make a person all that smart. America needs more nuclear power like a fish needs a bicycle. People in Wyoming may be fooled by this blather, but CleanTechnica readers aren’t taking the bait. Natrium was probably selected as the name of thus new nuclear technology because it sounds a little like “nature” or “natural.” That’s a great marketing ploy, but we’re not buying it. Frankly, the Bill and Warren show is more than a little disappointing.
Hyundai has officially debuted its Ioniq 9 in advance of the LA Auto Show, with a concept car-like interior that lets you swivel the 2nd row seats and turn your car into a living room.
We’ve been hearing about the Ioniq 9 for some time now, and the time has finally come for its release.
In an event in advance of the LA Auto Show, starting this Friday and with a media preview day tomorrow (which Electrek will be in attendance for), Hyundai showed off the Ioniq 9 which will officially be unveiled at the Auto Show (you can watch via livestream) on the morning of Nov 21st.
The car is what we expected – a large, 3-row SUV, much like the EV9, the Ioniq 9’s cousin that is built on the same platform by Hyundai’s sister company, Kia.
But it also has some features we didn’t expect – like a little more clarity on that “lounge-like” interior we heard about, which turns out not to just be marketing fluff at all. It actually is like a lounge, complete with la-z-boy style footrests and swiveling seats so you can face your friends. More on that in a bit.
The Ioniq 9 comes with a perhaps excessively-large 110.3kWh battery (that extra 300Wh makes a big difference), offering up to 335 miles of range on the Long-Range RWD model with 19-inch wheels. 20- and 21-inch wheels are also available, we imagine with lower ranges.
The large battery will retain the E-GMP platform’s excellent DC charging performance, with the ability to charge from 10-80% in 24 minutes, assuming you’re connected to a capable charger (Hyundai says 350kW “under optimal conditions”).
The Long-Range model will have a 160kW (215hp) rear motor, and an additional 70kW (94hp) front motor if you get the AWD model. Performance AWD will be available with 160kW motors on both axles.
The long range RWD model will do 0-100km/h (0-62mph) in 9.4 seconds, AWD in 6.7 seconds, and Performance AWD in 5.2 seconds (or, if you prefer 0-60, the Performance model can do it in 4.9).
The vehicle is large, as you’d expect out of a 3-row SUV, at 5,060mm (199.2in) long, 1,980mm (78in) wide and 1,790mm (70.5in) high. This is 2 inches longer than its sister car the EV9, and 1 inch less long than the Rivian R1S.
Exterior design keeps some of the design language of the (excellent) Ioniq 5, but larger and more rounded-off. In particular, it keeps some of the dot-matrix/pixel aesthetic of the lights.
I have to say I don’t love the roundedness of it – the design of the Ioniq 5 feels extremely consistent with a lot of straight lines throughout, whereas the rounded hood and extended rear end of the 9 spoil that consistency to some extent (and speaking of the rear… it almost seems a little hearse-like, to me).
Incidentally, with the Ioniq 5 and EV6, one is more boxy and the other is more rounded – and the same thing has happened with the Ioniq 9 and EV9, only in reverse. The Ioniq 9 is more rounded and the EV9 is more boxy. So, once again, these two similar vehicles have differentiated themselves enough that we expect the market will be split, with many customers liking one and disliking the other, meaning little cannibalization between the two.
The interior seems incredibly spacious, though so far we haven’t had a chance to experience it ourselves. Most 3-row SUVs in this size class do have somewhat cramped third rows, so we’re curious if Hyundai has managed to do some sort of magic in that respect.
And in addition to rear and frunk storage (with a frunk capable of holding 88L in RWD and 52L in AWD models), the center console offers a large amount of storage inside (18.2L, split between an upper and lower tray), and can be slid back and forth to allow easier movement between front or rear seats.
And speaking of magic, Hyundai has actually done something new here – an interior with swiveling middle seats, to turn the car into a lounge.
We’ve seen similar interiors on countless concept cars, but understandably they never make it to production. It’s definitely an attention-grabbing feature, but who really uses their vehicles like that?
Well, Hyundai thinks that people will, so it’s offered swiveling 2nd-row seats to allow for this. However, it says that these seats will be available “in selected markets only,” and it has declined to say exactly which markets those are yet. We also imagine this will only apply to the 6-seat configuration, rather than 7-seat.
The seats don’t just swivel though, they also recline and have a leg rest. Hyundai is calling these its “Relaxation Seats,” and the first and second row seats will both be capable of this feat. It says this will be particularly useful for people who want to get comfortable during vehicle charging (though, on an optimal 350kW charger, 24 minutes is hardly much time for a nap).
And that charging will be accomplished via a NACS port – making this, we think, the first non-Tesla vehicle to debut and be sold with only a NACS port at any time in the model’s existence. Other E-GMP vehicles are switching over to NACS, but the Ioniq 5 for example has been out for many years now, so there are lots of CCS Ioniq 5s out there, but that won’t be the case for the Ioniq 9.
Like other E-GMP vehicles, it will be able to discharge the battery via vehicle-to-load (V2L) to power devices, though we didn’t get clarity on how much total output it will have. Other E-GMP cars usually top out around 1.8kW, so enough to run some regular outlets, but not enough to power a house.
The Hyundai Ioniq 9 will be available in Korea and the US in the first half of 2025, and then will come to Europe and other markets later. The US version will be built at Hyundai’s plant in Georgia – another example of a car brought to the US by the domestic sourcing provisions of President Biden’s EV push (and which could be put into Jeopardy if Dumb & Dumber get their way in attempting to kill this boon for US manufacturing).
We don’t have pricing or all tech specs yet, so stay tuned as there’s still more to come.
Also, you can watch the official debut livestream over at Hyundai’s website, starting at 9:10am PST November 21st. And Electrek will be at the LA Auto Show to ask around and see if we can get any lingering questions answered.

Honda has been promising to unlock the power of all-solid-state EV batteries for several years. Today, we are getting our first look at the progress. Honda unveiled a demonstration production line as it continues to advance promising new battery technology.
By 2050, Honda wants all its products and corporate activities to be carbon neutral. Although electric vehicles are essential to this mission, Honda believes improvements are needed.
Since the battery is such a critical component for EVs, the company aims to unlock more driving range at a lower cost with new chemistries.
Honda is developing all-solid-state EV batteries in-house to power up its next-gen vehicles. It’s not “merely trying to establish a lab-level technology,” Honda is eyeing mass production in the coming years.
On Wednesday, Honda unveiled its demonstration production line for all-solid-state EV batteries, giving us our first look at the progress.
The line is located at Honda’s R&D facility in Sakura City, Tochigi Prefecture, Japan. Honda will use the demo line as a preface for mass production while determining the basic specifications of the battery cells.

Honda is launching EVs with all-solid-state batteries
Honda plans to launch electric models with the new all-solid-state battery tech in the “second half of the 2020s.”
The new demo line replicates the processes required for mass production. It covers around 295,000 ft2 (27,400 m2) and is already equipped with the tools to verify each production process, including weighing and mixing electrode materials, coating, and roll pressing electrode assemblies. The line also supports the formation of cells and the assembly of the module.
After the new facility was completed this spring, all the equipment needed for verification is now in place.
Honda plans to begin production on the new demo line in January 2025. With a highly efficient production process and a wide range of use cases, including automobiles, motorcycles, and aircraft, Honda aims to slash battery costs.
To speed up development, Honda is conducting “speedy research” in two main areas: material specifications and manufacturing methods.
Ahead of its 2050 carbon neutrality target, Honda aims for 100% of global vehicle sales to be EV or FCEV by 2040. Honda believes the new battery tech will be its differentiator.

There are typically a few common factors that make it hard to enjoy a bit of speed, but unlike most electric scooters on the market, Ausom managed to get just right with their new Leopard DT1 pro scooter.
Of course, given that you’re in a safe area where it’s legal to get some speed going. Going fast on an electric scooter typically means you start worrying about things like how expensive it’s going to be, braking power, handling, suspension, and battery life. Fortunately in this case Ausom created a powerful 2*1000w motor scooter that’s both fast and feels stable enough to make you want to go faster than 41 mph.
For a limited time, get an extra $50 off with promo code Electrek50 for Black Friday.
Even if you’re not planning to go the top speed, 2000 watts of motor in the scooter’s race mode setting is enough torque to have plenty of fun. On top of the fun aspect of having that much power instantly, if you ever need to go up a steep hill or need to accelerate quickly in order to get out of a potentially dangerous spot in traffic, the Ausom dt1 pro will do it without hesitation.
Now if you’re going to flip on that dual motor function you’ll be rest assured when it comes to braking because Ausom included E-ABS front and rear hydraulic brakes that can give you some serious braking power. On top of that for even more safety they included some stylish turn signals which are beautifully integrated into the natural shape of the scooter rather than having some protruding signals. There’s also a headlight and rear light for further visibility.
Another factor to consider for high speeds is battery life and range, but thankfully aside from coming with a 52v 18.2 ah battery and 47 miles of range the scooter also comes with easy-to-use controls to switch from different modes. If you need to get the most distance out of the battery, being able to quickly and easily switch to a single motor and also go to eco-mode makes a huge difference. To navigate the control, the company uses a big LCD screen that can quickly give you a reading on speed, mode, battery life, and more. For charging, Ausom knows how to deliver with the use of Dual-port charging for quicker and safer power-ups in around 4-5 hours.
For security, Ausom included an NFC security lock, which, unlike a traditional metal key, takes just a tap to unlock. In terms of overall features, Ausom includes some pretty convenient and smart features. For those who live in an urban area, you’re probably not a stranger to using an air tag on things like motorcycles or bikes for tracking purposes. Ausom had that thought out and included a special slot to hold an air tag. They also include a USB-A and USB-C charging port in order to charge your phone.
At just $1,099 (with promo code Electrek50) Ausom is packing a ton of value here with the Leopard dt1pro. Balancing out price, speed, and good handling is not easy but Ausom’s thick tires and swing arm suspension make it comfortable even when rolling down something like a steep curb or getting over some thick obstacles on the road.
Normally electric scooters might feel scarier to ride compared to bikes but the size and construction of the dt1pro was designed to be comfortable and easily maneuverable even at high speeds. For an even better deal, you can use promo code Electrek50 for $50 off the Leopard DT1, DT Pro, or the Gallop SR1 E-scooters from Ausom. If you’re looking for a bigger discount feel free to use code Electrek110 for $110 off the GX1 E-Scooter.
